Merge PDF Files
A permit packet is never one file. It is a site plan from the architect, a scanned application from the city, a signed contract, an insurance certificate and four pages of product data sheets. Drop them all in, drag them into the order the reviewer expects, and download one PDF.
How it works
- Choose the PDFs, or drag them onto the box. Add as many as you need, in any order.
- Use the arrows to sort them. The first page of every file is shown so you can tell them apart without opening anything.
- Download. One PDF comes back, with every page in the order you set.
What you get
- Any number of PDFs, combined in the order you choose
- A thumbnail of each file, so you never merge the wrong revision
- The page count of every file, and of the finished document
- Original page size kept, so a mixed letter and 11x17 set still prints right
- No watermark, no page limit, no account
- Nothing uploaded, because the merge happens in your browser
The permit packet problem
Most building departments want one upload. Most of what goes into it arrives as separate files from separate people, usually on the morning it is due. Emailing the reviewer eight attachments is how a submission gets rejected as incomplete, and a rejection costs a week even when nothing was actually missing.
Merging is also the difference between a proposal that reads as a document and one that reads as a folder. A cover letter, the estimate, the scope, the insurance certificate and the warranty, in that order, in one file, is a professional package. The same five files zipped together is homework for the customer.
Order matters more than people think
Whoever opens your merged file reads it top to bottom and stops when they have what they came for. Put the thing they asked for first. An adjuster wants the scope and the photos; a plan reviewer wants the application and the drawings; a general contractor chasing a payment wants the invoice, then the lien waiver, then the backup.
The arrows on each file move it one position at a time, and the number on the left is its place in the finished document. Nothing is committed until you download, so reordering costs nothing.
Nothing is uploaded
Every other free merge tool sends your files to a server, joins them there, and gives you a link back. That is a signed contract, a customer address and a license number sitting on a machine you do not control, and on most of those sites the file is kept for hours afterwards so the link keeps working.
Here the merge runs inside your own browser using a library that loads from this site and then does all the work locally. You can test it: load the page, turn your internet off, and merge anyway. It still works, because there is nothing to connect to.
What it does not do
It will not open a PDF that needs a password to view. Open it in your reader, save an unprotected copy, and merge that. It also will not compress the result, so a merged file is roughly the size of its parts added together. If the packet is too big to email, the usual culprit is scanned pages, and the fix is to rescan at 200 dpi black and white rather than 600 dpi color.
If you need to pull pages out rather than put files together, use split a PDF. If the packet is right but the pages are in the wrong order, use delete and reorder pages.
Questions people ask
Are my files uploaded?
No. The merge happens in your browser, on your device. There is no server here that receives the file, no account, and no copy kept.
How many PDFs can I merge?
There is no fixed limit. Your device is doing the work, so a very large packet on an old phone will be slow, but a normal permit set of ten or twenty files is instant.
Will it keep my page sizes?
Yes. Each page is copied at its original size and orientation, so a letter sized contract and an 11x17 drawing come through as they were.
Do bookmarks and form fields survive?
Page content, images and text survive exactly. Interactive form fields and bookmarks are not carried across, so if you need a fillable field to keep working, merge after it has been filled and flattened rather than before.
Is there a watermark?
No, and there is no page limit and no paid tier. The site is paid for by advertising on the page, not by holding your document hostage.
Can I merge on a phone?
Yes. Choosing files works from your phone storage, your camera roll or your cloud drive, depending on which picker your phone shows.
